` points where it Iis most needed, without waste,

The following is a description of our invention, reference being had tothe accompanying drawings.

Figure 1 is a top viewof our device. Fig. 2 is an end view of thesame.Fig. 3 is au inside'view of the lower half of the box', and Fig. 4 isAau, inside View o t' the upper h'alf ot' the same. 'l

A A are the flanges; 13 the oil-box, and Cv C the bearing.- 1) is achamber constructed insideof the upper halt' of the box, aud'com---1nuuicates with theoil-box B by'ineaus ofthe pipes b b; and'D is achamber constructed in-. side of the lower half ol' the box. These chamfbers communicate with the jonrnalj` and bearing by means ofthe openingsH and S S.' M

ll/ l and NV N are grooves iu the bearing cut in the sides of the lower'halfof the box, 'and K. :K .is a similar groove cut iu the upper half.,'.ll1 e groove K K communicates'di'rectly with the o/il-box B: by meansof the pipes a a. The groove M M communicates with-the chamber D b'ymeans 'of 4the holes IS S5S-S,'and the groove N N by means ofthe openingH. The chamber D connects with the chamber D when the two parts orf,the.` boltV arejoined-to- LA, portion .ofthe'oil-'f-rom the box Bis oar--ried bythe pipes a a directly to the journal,l

audisdistributed, by.v means of ythe groove'K K, over its 'entirelength. The rest of the oil -4 from the box Benterslthe upper chamber,D', through the pipes'hband lls both chambers.

pipes 'a a, and, by its motion, creates a suc.

tion throughv the holes'S S. By this means the bil which is in the lowercl1amber,-D,'is

drawn through the holes S S, and, by means of the'groove M M, isbrought" into contact with the entire length of the journal.

In the. groove -N N thereis an opening/H, vwhichopens downward intotheflower chamber, D. The upper edge of the groove N N, whichv isformed. by the lower edge ofthe upper half ofthe box, ismade sharp, andin--snch a manner as to scrape vthe oil from the journal .as itrevolves. rlhis oii'then collects in the `'groove N N, and passesthrough the opening -l .into the lower chamber, VD, whence-it is drawninthe direction of the arrows, as shown in Fig. 2, to theqvacuurn at S Screated by the revolution of the journal.'

' The journal is thus constantly snppliedrwith l oil, which, by means ofthe grooves, is equally istributed,.and the surplus oil, which wou lotherwise Work out at the ends of the b ea. ings,.pas ses through theopening H and is used again. f

We vclaimas our invention-'- l. The'combination, in journal-boxes ofrotary steam'egines and pumps,.of the chambers D and D with the pipes bb, the opening H, and the holes S S, substantially as and for thepurposes' hereinbefore described. f

2. The grooves K'K, M M, and NN, the, l pipes a a, lthe opening H, and"theholes S S,

when the several .parts are combined in .journal-boxes of rotary steamengines and pumps,

in the manner and for the purposes substantially as specified.
